Safety

CARPET PULLER SAFETY GUIDELINES

• Never stand in line of pull in case the rope breaks or the pull bar lets loose.

• Always have remote switches in hand.

• Do not allow yourself or others to become entangled in pulley, rope, winding shaft, or pull bar.

• Do not use any other type of rope that does not meet NFE specications (less than 6-8% stretch, 13900 pound tensile strength).

• Rope should always pull straight into the machine, never at an angle.

• Never have machine at an angle where the rope winds sideways on the shaft. This could cause the rope to wind improperly on the shaft

and damage the rope.

• Ensure hook is securely tied to rope.

• Know the working load limit (WLL) of the rope being used and ensure it is appropriate for the application.

• Do not bend rope around unprotected, sharp corners. Do not use over rough surfaces without chafe protection.

• Motor should not be run without a fan cover in place.

WARNING: DO NOT USE CABLE. DOING SO COULD CAUSE PROPERTY DAMAGE OR BODILY INJURY.

WARNING: THE IMPROPER USE OF ROPE IS DANGEROUS, AND COULD RESULT IN BODILY INJURY OR DEATH. ROPE WILL FAIL IF

WORN, DAMAGED, ABUSED, OVERLOADED, OR NOT PROPERLY MAINTAINED.

WARNING: DO NOT STAND WITHIN RECOIL (SNAPBACK) AREA, UNLESS PROTECTED BY SCREEN. FAILURE TO DO SO COULD

CAUSE SERIOUS BODILY INJURY OR DEATH.

WARNING: DO NOT USE ANY OTHER TYPE OF ROPE THAT DOES NOT MEET NATIONALS SPECIFICATIONS. OTHER TYPES OF ROPE

WHICH MAY HAVE THE PROPER WLL, GENERALLY HAVE A HIGH ELONGATION OR STRETCH FACTOR, MAKING MACHINE POTENTIALLY

DANGEROUS FROM ROPE SNAP BACK RESULTING IN BODILY INJURY OR DEATH. ONLY USE NATIONAL #71-P33 REPLACEMENT ROPE

FOR SAFE OPERATION. FAILURE TO DO SO COULD CAUSE PROPERTY DAMAGE OR BODILY INJURY. NEVER USE CABLE.

Components and Assembly

PRE-OPERATION INSPECTION

• Make certain protective screens are in place before operating (Figure 6).

• Ensure rope guard is in place. Guard should be in the down position to cover rope

and drive shaft (Figure 7).

• Inspect weld points on pull bar for security.

• Inspect clamps to ensure they are not bent or damaged.

• Inspect for loose or damaged parts on the pulley wheel, pulley housing, pulley hook

and pin.

• Inspect rope for cuts or fraying. Replace frayed or damaged rope with NFE stock

#71-P33. Ensure hook is fastened correctly to rope. Do not tie knots in rope.

• Keep gripper strip pins clean and free from debris. Replace damaged pins with new

gripper strips, NFE stock #71-P7. Clean dirty pin strips with a stiff wire brush. Brush

in direction of pin angle.

• Inspect wiring for cuts or damage and switches to ensure they are in good working

condition. Switches must return to the off position when released.

• Ensure ll plug is installed on gear unit.

• Pulley should be inspected before each use. Loose or damaged parts should be

replaced immediately.

• Inspect area to be removed for any possible obstruction on oor, defects in carpet,

cross seams, oor outlets, columns or posts.

• Remove all debris from carpet area that machine will be anchored to. Keep pin

base clear of obstructions. Dirty, damaged, or missing pin strips could cause ma-

chine to slip.

Operation

FIG. 8

GENERAL OPERATION

SCORING THE CARPET

• Score carpet in 6 foot widths, or narrower if the carpet is very strong.

• Carpet should be pulled lengthwise whenever possible. Carpet is the weakest,

especially in woven or axminister construction, when pulling cross breadth. Watch

for cross seams. If there is a small piece of carpet attached to the pull bar and the

pull bar meets a cross seam, the pull bar will jump forward rapidly.

HOOKING UP THE PULL BAR

1. Loosen the carpet approximately 12-18” from the wall where the tearout will begin.

(The #99 Cobra Clamp is an easy way to get ahold of carpet to pull away from the

wall).

2. Attach pull bar to loosened carpet. Make sure the carpet goes all the way through

the channel bar, reaching out the other side (all 3 sides) (Figure 8).

3. Insert bar and tighten “C” clamps. Make sure channel bar ts at into the channel of

the clamping bar (Figure 8). Failure to do so could cause bar to disengage carpet

prematurely.

ROPE SET-UP

MOVE MACHINE INTO PLACE SO THAT THE ROPE WILL PULL STRAIGHT INTO THE

MACHINE (FIGURE 9). IF ROPE IS PULLING AT AN ANGLE, STOP THE MACHINE

AND RELEASE PRESSURE ON ROPE.

PULL ROPE SHOULD ALWAYS BE AT A 90 DEGREE ANGLE TO THE MACHINE.

NEVER HAVE MACHINE AT AN ANGLE WHERE THE ROPE WINDS SIDEWAYS ON

THE SHAFT (FIGURE 9). THIS COULD CAUSE THE ROPE TO WIND IMPROPERLY

ON THE SHAFT AND DAMAGE THE ROPE.

Usually, hook rope up to the center hook on the pull bar. Hooking to the right or left shift

hook on the pull bar will keep the bar at an angle to stay clear of a wall or object.

POSITIONING MACHINE FOR STRAIGHT OR DOUBLE PULL

Single pull will remove approximately 20 ft/min. Double pull will remove approximately 12

ft/min. If machine seems bogged down when pulling on single pull, immediately shut off

machine and switch to a double pull (Figure 10).

1. To adjust machine base, make sure tension is released from rope and pull bar. Lift

WARNING: NEVER ATTEMPT TO GUIDE ROPE BY HAND ONTO SHAFT

WHILE UNDER POWER. OPERATOR COULD

BECOME ENTANGLED IN WINDING SHAFT CAUSING SERIOUS INJURY.

WARNING: NEVER TOUCH ROPE OR WINDING SHAFT WHILE OPERATING.

DOING SO COULD CAUSE BODILY INJURY.

WARNING: NEVER STAND IN FRONT OR NEXT TO PULL BAR OR TRY TO

PULL ON IT WHEN ROPE HAS TENSION ON IT. DOING SO COULD CAUSE

SERIOUS BODILY INJURY.

base using front screen (Figure 11) and position for a straight pull.

2. Release drive shaft from pin to quickly extend the rope out to the pull bar.

3. Either hook rope onto pull bar (Figure 12) or hook pulley onto pull bar and insert

rope hook through pulley to attach to the rope (Figure 12.1).

4. See Figures 10 and 10.1 for double pull instructions.

5. With power off, take up slack quickly by hand. Re-engage drive shaft to pin. Rope

feeds in from the bottom of the drive shaft (Figure 13).

Note: If you need to make any adjustments on pull bar, be sure all pressure is released

on pull rope. Ensure pull bar is always free from obstructions, such as posts or other solid

objects. If you should hit an obstruction, release tension on rope before adjusting pull bar.

6. If strength of carpet does not allow 6 foot width to be pulled without breaking the

carpet or stalling the machine, cut carpet into smaller widths or convert from single

to double pull mode (Figure 10).

Note: Always release tension on rope and pull bar when machine is stopped. If using an

angle pull from one room to another, ensure hallways are blocked off.

OPERATING CONTROLS

Switches are spring activated. Both switches need to be moved off-center to keep the

machine running (Figure 14).

• Left Switch (Power Cord On/Off): center is off, left is on.

• Right Switch (Motor Cord): center is off, right pulls rope in, and left releases rope

out.

FIG. 13

WARNING: NEVER STAND IN FRONT OR NEXT TO PULL BAR, BETWEEN

PULL BAR AND THE MACHINE, OR TRY TO PULL ON THE BAR WHEN ROPE

HAS TENSION ON IT. DOING SO COULD CAUSE SERIOUS BODILY INJURY.

WARNING: NEVER TRY TO OPERATE MACHINE UNATTENDED. DO NOT

ALTER SWITCHES OR GUARDS. DO NOT DEFEAT A SAFETY DEVICE.

Maintenance

FIG. 1

PREVENTIVE MAINTENANCE

• Inspect for damage on power cords, rope, switches, and guards. Worn or broken

cords and switches could result in electrical shock and should be replaced.

• Pull rope should be replaced when excessive wear (reduction in diameter), frays,

or cuts are visible. Use #71-P33 Replacement Rope.

• Oil level in gearbox should be checked once per year. Remove level screw on side

of gearbox; ll if needed (Mobil SHC 634).

• Drive shaft and pillow block bearing should be greased for free shaft movement to

engage and disengage.

• Examine pulley for free movement of pulley wheel and to ensure pulley frame and

hook are free from damage.

CLEANING

Properly selected and installed electric motors are capable of operating for long periods

with minimal maintenance. Periodically clean dirt accumulations in and around vent

openings, preferably by vacuuming to avoid embedding dirt in windows.

Periodically check that all electrical connections are tight.

ROPE

Replace rope if frays or cuts are noticeable.

• To remove rope, lift guard and release drive shaft pin. Pull rope off of drive shaft.

Cut knot off at the end of rope to remove.

• To install rope, insert rope through hole in drive shaft on the sidewinder guide. Tie

a knot on end of rope to secure. Take up slack quickly by hand, then re-engage

drive shaft pin. Release guard down into place. Turn switch to forward to wind rope

onto drive shaft.

Secure rope hook to end of rope with knot as seen in Figure 1.

PULL BAR

Internal clamping bar could build up with residue.

1. Remove bar.

2. With gloves on, scrape off residue with a razor scraper or wipe off with a solvent.

3. Inspect clamp for proper condition.

4. Ensure “C” clamps are not bent and are working properly.

5. Re-place bar.

GRIPPER STRIPS

Use protective cover over gripper strips when the machine is being transported or not in

use. Keep gripper pins free of debris.

WARNING: ENSURE POWER SUPPLY IS DISCONNECTED BEFORE SERVIC-

ING MACHINE OR REMOVING ANY COMPONENTS. FAILURE TO DO SO

COULD CAUSE ELECTRIC SHOCK.

402294_71_REVC

Maintenance

To remove debris, use a wire brush. Be sure to wear gloves and brush over pins in a

downward motion (from back of machine to front of machine), removing debris caught in

pins (Figure 2). Use a long shank screwdriver to pry out debris that is embedded into the

pins.

REPLACING GRIPPER STRIPS

1. Remove (6) phillips head screws.

2. Remove damaged gripper strip and replace with a new gripper strip.

3. Gripper strip pins are angled. The angle faces towards the front of the machine

(Figure 3). Repeat with (4) remaining gripper strips.

4. Re-place screws (Figure 4).

LUBRICATION

Figure 5 shows the correct locations for the oil ll plug, the oil level plug, and the oil drain

plug on the reducer. Plugs may vary in location on the sides of the reducer.

For new reducers, change the oil 120 hours after the reducer starts operating (based on

8 hours per day operation). After the rst change, change oil every 2,000 operating hours

or every six months.

Use Mobil SHC® 634 gear lubricant or a similar synthetic gear oil. ISO viscosity grade

460. Available from National, stock #1450-40, 1 quart.

ADDING/CHANGING OIL

To add oil:

1. Remove both the ll plug and oil level plug.

2. Place oil in the ll plug hole. Keep adding oil in until it starts to come out of the oil

level plug hole.

3. Replace plugs.

To change oil, rst drain oil from unit by removing the drain plug. Re-place drain plug and

complete steps 1-3 for adding oil.

CHANGING THE OUTPUT OIL SEAL

1. Remove the rope shaft and gear reducer from the unit.

2. Place some form of support, (2 x 4 etc.), under the gear reducer shaft to keep it

from bending. Drive out the gear reducer shaft pin and pick out the old seal.

3. Clean out the area where the old seal was; install the new seal by carefully press-

ing it in.

4. Re-install drive pin; put loctite around the middle of the pin and carefully press into

the shaft.

5. Re-install rope shaft.
